Could you test with a clean profile, please (it's a huge gape between ESR and FF23).

It that doesn't change anything, did you know if MS is aware of the issue? Did you report it?

But I'm almost sure I saw a bug passing about this issue (XBAP WPF-Application).
Are you sure the support of this plugin is not finished (or discontinued)?

[Patrik Heim]

I have tested it on different maschines with new installation of FF23 and it didn't work. 
I don't know if MS is aware of that issue and i haven't reported to them.

Acording the webpage of MS http://msdn.microsoft.com/en-us/library/aa970060.aspx is Internet Expoler an Firefox supported for XBAP WPF-Applications.

Does it work when you go to about:config and set plugins.load_appdir_plugins to true?

I have changed this config parameter. Now the Plugin is shown again in Plugins Page (Tools-> Add ons), but the broswer window shows first white an after abaut 20sec it turn to black and nothing happens. Normaly it should come up the download page of the XBAP Application.

At least in this case we are not going to fix the bug. Microsoft needs to update their plugin to install via the registry instead of dropping into the app directory (and they may also need to fix the blackness issue, but that's separate).

Patrik, about the other issue (whiteness/blackness issue), there is bug 893671.
